Some embodiments include a flexible, pressure-balanced cable assembly. The cable assembly has a tubular-shaped flexible outer sleeve that surrounds an electrical cable. A plurality of seals is positioned along the length of the flexible sleeve within the space formed between the inner surface of the flexible sleeve and the outer surface of the electrical cable. The seals partition the space into a plurality of individual chambers. Each chamber is filled with dielectric fluid. The seals are independently and bi-directionally movable in response to a pressure difference between the inside of the cable assembly and the external environment thereby balancing the pressure between the inside of the cable assembly and the external environment.

Flexible electronically functional fibers are described that allow for the placement of electronic functionality in traditional fabrics. The fibers can be interwoven with natural fibers to produce electrically functional fabrics and devices that can retain their original appearance.

A self-retracting coiled cable having a variable length along a center line can include an outer insulator sleeve having a longitudinal axis. The self-retracting coiled cable can also include a spring material extending along the longitudinal axis of the outer insulator sleeve. The spring material can hold the outer insulator sleeve in a helical shape around the center line. The spring material can also allow the self-retracting coiled cable to expand upon an application of an axial force to an end of the self-retracting coiled cable, thereby increasing a length of the self-retracting coiled cable, and to retract upon a removal of the axial force from the end of the self-retracting coiled cable, thereby reducing the length of the self-retracting coiled cable. The self-retracting coiled cable can further include multiple wires extending along the longitudinal axis of the outer insulator sleeve and disposed symmetrically around the spring material.

Twisted pair cables incorporated separators with cooling channels are described. A cable may include a plurality of twisted pairs of individually insulated electrical conductors, and a separator extending lengthwise along a longitudinal length of the cable may be positioned between at least two of the plurality of twisted pairs. The separator may include a flexible body configured to maintain the at least two pairs in a predetermined configuration. A first channel extending lengthwise may define a longitudinal cavity through the separator, and at least one second channel may extend from the first channel through the flexible body to an outer surface of the separator. Additionally, the cable may include a jacket formed around the plurality of twisted pairs and the separator.

Flexible cables may include multiple power, ground, and signal traces, and include EM interference suppression devices within the cable itself. Signal traces may be shielded by ground traces. The body of a cable may be divided into lateral portions through which different types of traces extend. One lateral side of a cable body may include a stack of power traces, while another lateral side of the cable body may include ground and signal traces. EBG patterns may be incorporated into ground traces. Capacitors may be positioned within the cable along its length, mounted between power and ground traces, for decoupling.

A fluororesin cable can include an electric wire having a central conductor covered with an insulator, an inclusion, a tape made of a resin, and a sheath made of a fluororesin. The inclusion is arranged along the electric wire. The tape is wound around an outer periphery of an aggregate of the electric wire and the inclusion. The sheath entirely covers the aggregate and the tape. Here, a material for the inclusion is harder than a fluororesin material constituting the sheath.

Systems and methods presented herein provide for elastomeric and flexible cables. In one embodiment, an elastomeric cable comprises an elastomeric core (e.g., a stretchable polymer) and at least one cabling component wound about the elastomeric core along a length of the elastomeric core.
